Abstract:
The role of the power system operator or independent system operator in restructured power system is to maintain a balance between generation and demand. Traditionally, generation rescheduling is carried out in power system to maintain the power balance ignoring the demand side balancing. A PSO based optimization algorithm for dispatch of generation and load (DGL) is proposed in this paper. The dispatchable resources considered are generating units and demands. A framework for DGL is presented which is based on load shifting cost bid by the customer. The operating cost of the power system decreases as the costlier peaking units are off. The proposed algorithm is tested on IEEE 30 bus system, 10, 20, 40, 60, 80 and 100 unit systems. The results validate the efficiency and applicability of the proposed algorithm in deriving economic benefits.
